Outcome of Snodgraft (G-TIP) Urethroplasty for the Treatment of Primary Distal Hypospadias

Abstract

Background: One of the most prevalent congenital abnormalities of the external genitalia in boys is hypospadias. One common method of treating distal penile hypospadias is tubularized incised plate urethroplasty. However, there are a few side effects of this procedure, such as neourethral stenosis, meatal stenosis, and uretho-cutaneous fistula. In distal hypospadias, snodgraft modification has been suggested as a way to lower the risk of meatal and/or neourethral stenosis. Objective: To find out the outcome of Snodgraft urethroplasty technique in distal penile hypospadias. Materials and Methods: This prospective observational study was carried out in the Division of Pediatric Surgery, Bangladesh Shishu Hospital & Institute from January 2020 to March 2022. Total 40 patients having distal variety of primary hypospadias were included by selection criteria. All patients with single stage urethroplasty using inner prepucial skin graft has been done. Statistical analysis was carried out using the Statistical Package for Social Sciences version 26.0 for Windows. Results: Majority of the patients had subcoronal variety 27(67.50%) followed by coronal 10(25.0%) and glanular hypospadias 3(7.50%). More than three fourth (77.5%) patients had urethral plate width 4-8 mm. Wound infection was developed in two patients out of 40, one coronal and one subcoronal. Four patients had developed urethro-cutaneous fistula among them one was coronal three was subcoronal. No meatal stenosis and urethral stricture was found in follow up period. Conclusion: The patient with Snodgraft (G-TIP) modification in repair of primary distal hypospadias leads to reduce the complication.
